Good Solderability Nickel Welding Strips For Battery Packs

Nickel Strip 99.96% High Purity Welded Pure Nickel Strip

Product Description

The nickel masterbatch is smelted in vacuum with a purity of 99.9%. The finishing mills are all rolled by imported multi-rollers, the thickness is the thinnest 0.02mm, and the tolerance is controlled within ±0.001mm. The hardness of the material is uniform. state) HV 75~110, 1/4Y (quarter hard) HV 110~140, 1/2Y (semi hard) HV140~180, 3/4Y (three quarter hard), Y state (hard state) HV180~220, the narrow-band process is cut from strips, and the cross-section is a regular rectangle. This process is precise, difficult, and the product is excellent. The narrowest 1mm width, the minimum product size is 0.02*1mm, and the curvature is less than or equal to 0.5mm/M , The product has good welding performance, good electrical conductivity and oxidation resistance, good finish, and complete state specifications.

Surface Quality

• The surface of the strip should be smooth and clean, and there should be no wind layer, cracks, bubbles, thorns, pressure and folding inclusions;
• Slight local defects such as scratches, spots, pits, indentations and roll marks are allowed. Slight oxidation color, darkening and slight local oil stains are not allowed. Scrap basis;
• The strip should be straight, but slight waves are allowed; the side curvature of the strip is greater than 3 mm per meter of cloth.
  Application example: used in the manufacture of chemical equipment such as pipelines, heat exchangers, evaporators, heaters, reactors, etc.; targets for various coatings; electrodes, etc.

Nickel strip characteristics

Good gloss, ductility, weldability
The difference between N4 and N6 pure nickel belts: The difference between N4 and N6 lies in the content of C, namely: low carbon pure nickel and ordinary pure nickel respectively

N4, N6 correspond to Ni201 and Ni200 in ASME II, namely low-carbon pure nickel and ordinary pure nickel

(ie N4/Ni201, N6/Ni200)

N4 Ni%=99.9%, C%=0.01%Max,

N6 Ni%=99.5%-99.6% C%=0.10%Max

Corrosion resistance of pure nickel

Pure nickel is particularly resistant to alkali corrosion, and is relatively stable in high temperature or molten alkali, so it is mainly used in the alkali industry. Nickel is extremely stable in seawater and salt solutions and organic media (such as fatty acids, phenols, alcohols, etc.) at room temperature. Not resistant to inorganic acid corrosion, also unstable in acetic acid and formic acid.

According to GB2054-2005, the difference between N4 and N6 is:

1. Chemical composition, the content of N4 C is less than 0.02%, the content of N6 C is less than 0.15%, and the content of other elements is the same;

2. Mechanical properties, in M state, N4 Rm≥350MPa, N6 Rm≥380MPa

Remarks: N4 and N6 are shown above, mainly because of the difference in C content. N4 is called low-carbon pure nickel, and the content of other elements is the same. Due to the low-carbon nature of N4, it is suitable for use in some specific situations, so it is better to communicate with customers. Use the environment or purpose to avoid unnecessary trouble.

Pure nickel belt: the nickel content is more than 99.95%. Pure nickel has excellent mechanical properties and high corrosion resistance in a variety of different environments. It also has magnetostriction and magnetic properties, high heat transfer, high Features such as electrical conductivity, low gas volume and low vapor pressure. It has good spot welding performance, high tensile tension and easy operation. Low resistivity (the first choice for notebook battery packs), which can pass currents above 50A, is the first choice for power battery packs.

Strip grade, condition, specification

Nickel strip: Nickel content is higher than 99.95%. Pure nickel has excellent mechanical properties and high corrosion resistance in a wide variety of environments. It also possesses magnetostrictive and magnetic functions, as well as high heat transfer properties, with high electrical conductivity, low gas volume and low vapor pressure. It has outstanding spot welding function, high tension and easy operation. Low resistivity (combined by laptop battery packs) can pass a current of more than 50A, which is a combination of power battery packs. This product of pure nickel wire manufacturers is mainly used to make nickel-metal hydride batteries. Lithium batteries, combined batteries and power tools, communication information, special lighting and other industries.
